Can anybody help me please? I recently purchased a used Rhoades Car Bike that I thought I would fix up. The problem is I'm missing a wheel/rim. I cannot find a 20" rim with a 3/4" bearing? ( the shaft the rim rides on is 3/4". ) The company charges a very expensive price for a new rim, and I was hoping to find a used one for now. Any help would be greatly appreciated.
